论文摘要
我们研究一类SU（N）Wigner 6J符号，涉及两个基本表示，并为此类别中的所有6J符号提供了明确的公式。我们的公式根据所涉及的表示的尺寸表达了6J符号，因此它们是N的功能。我们将这些显式公式视为有效分解SU（N）颜色结构的第一步，该颜色结构在组不变的方面。
We study a class of SU(N) Wigner 6j symbols involving two fundamental representations, and derive explicit formulae for all 6j symbols in this class. Our formulae express the 6j symbols in terms of the dimensions of the involved representations, and they are thereby functions of N. We view these explicit formulae as a first step towards efficiently decomposing SU(N) color structures in terms of group invariants.
